B. on slab, hold down gag (11) and siege (13) clamp slab decline 2685mm jointly, and after putting in place, on slab, hold down gag cylinder (12) and lifting hydraulic cylinder (6) are locked, complete the once decline of blank;
C. slab turning device (3) is through the driving of upset hydraulic cylinder (4), be turned to 90 ° by 20 °, slab guider (7) drives and stretches out 100mm through guiding hydraulic cylinder (8), the directive wheel of slab guider (7) contacts with slab, after putting in place, upset hydraulic cylinder (4) and guiding hydraulic cylinder (8) are locked;
When d. on slab, hold down gag (11) and siege (13) clamp slab decline 300mm jointly, siege (13) is put into slab on slab turning device (3), slab lowering or hoisting gear (5) continues decline 100mm under the driving of lifting hydraulic cylinder (6) simultaneously, after putting in place, lifting hydraulic cylinder (6) is locked, on slab, hold down gag (11) hold down gag cylinder (12) on slab drives simultaneously, and depression bar retraction 3085mm gets back to home position;
E. slab turning device (3) and slab guider (7) clamp the slab upset jointly, when slab is turned to 87.5 ° by 90 ° of vertical bases, slab guider (7) arrives the front extreme position of guiding, halt and lead and be retracted into home position, meanwhile, slab turning device (3) is under upset hydraulic cylinder (4) drives, and slab is turned to the fortune base position of 20 °, and the rear upset hydraulic cylinder (4) that puts in place is locked;
F. slab Traverse Displacement Unit (1), through the driving of traversing hydraulic cylinder (2), moves 890mm arrival by home position to the roller-way direction and puts the base position, and the rear traversing hydraulic cylinder (2) that puts in place is locked;
G. slab turning device (3), through the driving of upset hydraulic cylinder (4), is turned in-1 ° of process by 20 °, 0 ° of position, slab is put on the rolling line roller-way, and during to-1 °, upset hydraulic cylinder (4) is locked;
H. slab Traverse Displacement Unit (1), through the driving of traversing hydraulic cylinder (2), moves 890mm arrival home position by putting the base position to the induction furnace direction, after putting in place, completes whole ejection action.
